An apparatus

A apparatus comprising at least one sensor means for determining at least one proximate object, means for determining at least one parameter associated with the at least one proximate object and means for generating by ultrasound at least one tactile effect to the determined at least one proximate object based on the at least one parameter. An ultrasound transducer generates a tactile effect to the proximate object such as a finger or stylus where the tactile effect pressure wave amplitude, duration and direction may be based on the objects location, speed, angle and direction as well as the number of proximate objects. The sensor means for determining the proximate object may be a non-contact sensor means such as hover, imaging fogale sensor means. The ultrasound provides tactile/haptic feedback to a user of the device such as a display without the user contacting the display.
